| contents | We present a novel approach to optimize wind farm layouts for maximum annual energy production (AEP). The optimization effort requires efficient wake models to predict the wake flow and, subsequently, the power generation of wind farms with reasonable accuracy and low computational cost. Wake flow predictions using large-eddy simulation (LES) ensure high fidelity, while reduced-order models, e.g., the Gaussian-curl hybrid (GCH), provide computational efficiency. We integrate LES results and the GCH model to develop a machine learning (ML) framework based on an autoencoder-based convolutional neural network, allowing for a reliable and cost-effective prediction of the wake flow field. We trained the ML model using high-fidelity LES results as the target vector, while low-fidelity data from the GCH model serve as the input vector. The efficiency of the ML model to predict the AEP of the South Fork wind farm, offshore Rhode Island, was illustrated. Then, we integrated the ML model into a greedy optimization algorithm to determine the optimal wind farm layout in terms of turbine positioning. The optimized wind farm layout is shown to achieve a 2. 05\% improvement in AEP over the existing wind farm. |
